Mossberg 940 PRO Tactical M-LOK Barrel Clamp

In stock


You are probably aware that there are many M-LOK products being manufactured that are not directly made by Magpul.  There is even a company that claims that the M-LOK products they are selling are manufactured by Magpul.  They are not.  So buyer beware!

The screws that are included that attach to the T-Nuts for installation are of varying lengths.  Even Magpul uses these two different screw sizes for most of their M-LOK products - 10-24 x 3/8" button head cap screw or 10-24 x 7/16" button head cap screw.

To assist in solving this issue GG&G is including qty. (4) 10-24 x 3/8" button head cap screws with nylon thread locker patch with the GG&G Mossberg 940 Pro Tactical M-LOK configured barrel clamp.  This will allow you to use most Magpul manufactured M-LOK accessories, as well as other M-LOK products produced by other manufacturers.

Even with this proactive approach, please be aware that the web thickness of the screw hole on other manufacturers M-LOK accessories may negatively affect fitment.  It is important to note, the included screws however, work perfectly with GG&G manufactured M-LOK accessories.

If you are using a non GG&G M-LOK accessory, even when using the GG&G supplied screws, please check and make sure that as you tighten the screws into the T-Nut, supplied with your M-LOK product, that the screws do not bottom out or make contact with the bottom of the M-LOK pocket, prior to putting the firearm and accessory into service.

Mossberg 940 PRO Tactical M-LOK  Barrel Clamp

Mossberg 940 Pro Tactical Shooters have been calling us almost since the day the 940 Pro Tactical was introduced. Besides the standard accessories we make, they indicated they would prefer having a durable, aluminum M-LOK barrel clamp for the their 940 Pro Tactical Shotgun versus the factory provided plastic barrel clamp, (even if it wasmade  from of thermo-plastic).  Some shooters prefer mounting a sling attachment or other accessory at this far forward position. Customers have indicated the factory plastic barrel clamp has cracked as they attempted to tighten it to prevent it from sliding to the rear when the barrel heated up and there was tension on the sling mounted to the barrel clamp, or moving forward due to recoil. 

GG&G has a solution! The GG&G Mossberg 940 PRO Tactical M-LOK Barrel Clamp. First off, it is not a generic barrel clamp! It is CNC machined specifically to fit the barrel and magazine tube of the Mossberg 940 Pro Tactical 12gauge Shotgun. The billet aluminum two piece GG&G M-LOK Barrel Clamp provides Magpul M-LOK slots on both sides of the GG&G Barrel Clamp. The M-LOK slots are centrally located providing a super stable mounting point for sling mounts or light mounts, for light or heavy flashlights.
